Josh Hutcherson had better hold onto his butt, because once The Hunger Games opens March 23rd, he’s going to have to borrow note from Twilight on how to get by. Right now Hutcherson is enjoying the fun kind of fame, where he gets to go to award shows (like the 2012 People’s Choice Awards) and chat with MTV about on-set pranks.

Hutcherson answered questions sent into via Twitter, one of which was pretty damn funny. @jjussan asked, “I’ve heard a lot about pranking on the set… tell us one of the things that happened!”

Hutcherson came up with the perfect story:”They had a full life-sized dummy of one of our tributes that had gotten killed by a tracker jacker, and basically it’s all swollen and gnarly-looking and mangled, and Jennifer was out of her trailer so I took the dummy and put it inside her bathroom in her trailer,” Hutcherson explained. “I wasn’t there for the big moment when she saw it, which I can’t believe I missed, but I’ve been told that she actually peed her pants in reaction to it. So, I was pretty proud of myself and amazed that someone actually peed their pants in fear, because I didn’t know that happened.”

Classic. Anything related to celebs peeing themselves – nay – anyone peeing themselves sends even the stuffiest of us to laugh. Check out the video after the jump.
